Lots of public reports deal with the increasing gap between homologation results and real field pollutants and CO2 emissions. Our vision, since many years has been to develop the missing link between fuel and engine.
The fuel/engine co-optimization is an efficient and available solution to face the coming stricter regulation about CO2 and pollutant emissions. Matching the engine to the fuel is good for business and Earth.
In Europe, the European commission and Member States agreed that car manufacturers must reduce the divergence between the regulatory limit that is tested in laboratory conditions and the real world emission performance. To do so, the new real driving emissions (RDE) tests will determine whether a new car model is allowed to be put on the market.
The RDE procedure will be introduce in two steps:
• In a first step, car manufacturers will have to bring down the discrepancy to a conformity factor of maximum 2.1 for new models by September 2017 (for new vehicles by September 2019)
• In a second step, this discrepancy will be brought down to a factor of 1.5, taking account of technical margins of error, by January 2020 for all new models (by January 2021 for all new vehicles)
Nitrogen oxide (NOx) emissions limits for diesel vehicles are 80mg/km (Euro6). Now, the introduction of new RDE testing methods is a further tightening of the screws. According to Commission data, currently produced Euro 6 diesel cars exceed the NOx limit 4-5 times (400%) on average in real driving conditions compared to laboratory testing.
